JOHN VAN, OF oINoINNATI, OHIO.

IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 40,201, dated October 6, 1863.

To all whom it may concern.-

Be it known that I, JOHN VAN, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Cooking- Stoves; and I do hereby declare the following to be a full, clear, and exact description thereof. reference being had to the accompanying drawings, making part of this specification.

My improvements are chiefly directed to, first, a convenient provision for roasting, broiling, &c., in a common cooking stove or range; second, a construction of boiler-plates which insures tight joints while permitting the unrestricted expansion and contraction of the metal.

Figure l is a perspective view of a stove embodying my improvements. Fig. 2 is a longitudinal section thereof. Fig. 3 is ahori-' O, for a charcoal fire, and which, when not in use, may be covered by a plate, 0.

D and E are ash-pits for the main fire and for the charcoal fire, respectively.

F is a waterback to the main fire-place.

G isa damper for direct escape of the smoke when desired. The damper G being closed, the flame passes in a single broad sheet along the top H, back I, bottom J, and front K of the oven L, and escapes through an aperture, m, into the chimney M. A deflector, N, prevents the smoke escaping by a direct cut to the aperture m, and tends to equalize the heat at all parts of the oven. The portion K of the flue prevents the undue cooling of that part of the oven nearest to the Water-back and also assists in heating the contents of the latter. The general direction of the flame being nearly parallel to a plane transverse to the oven, and the shortest route of the flame being that obtained by hugging the top, bottom, and sides of the oven, the entire available heat of the flame is utilized, which is not the case where a portion of the course of the flame is in a plane at right angles to the above and its shortest course is not obtained by hugging the oven.

0 is a plate-warming closet.

P is a roasting-rack.

Q is a grid for roasting a steak.

It is a grid for broiling over the charcoal fire.

Beneath the boilerplates S are marginal flanges 'l, which enter grooves U U in the stove-top V and in the contiguous plates.

Some play is provided between the flanges and the grooves to compensate for expansion and contraction of the metal without opening the joints.

1 claim herein as new and of my invention 1. In the described combination with the grate A A, the broiling and roasting chamber B I), having in its floor a drop charcoal grate O, the whole being arranged and operating substantially in the manner and for the purposes set forth.

2. Constructing the top and boiler plates of a cooking-stove with loosely fitting marginal flanges and grooves T U U for the objects explained.

In testimony of which invention I hereunto set my hand.

JOHN VAN.
